Cool manual! I just didn’t figure out what is it for, but definitely not for: Outlook states you have unread mail but shows an empty folder

And Steve: Nice that you’re trying to help, but even if I consider myself an experienced user of this crap OS, I didn’t have the mind power to guess which of the ton of settings are you reffering to, so your advice was also useless.

I had the same problem; after reading the previous fixes–not trying them since they don’t work, I checked my iPhone and saw the culprit. I read the message on the device and in Outlook the unread message went away. I read the message yesterday in the Outlook client but it was apparently showing as unread on my device. Strange.

All you have to do is move the mails to another folder (Test) and then click on “Click here to view more on Microsoft Exchange” which will show the unread mails saved on server. Select those unread email and mark as read.

You can use this option without moving to a new folder.
Whilst the folder with the supposed unread mail is highlighted just type read:no in the search box.
Chances are they have been read on another device.
Works a treat.

We also had this problem. It was caused by calendar items in a mailbox without an agenda. Outlook doesn’t know what to do with those items. Right clicking “mark all items as unread” on the top folder solved it.

The “read:no” options worked for me. Only suggestion I have is if you have many folders and only one or two of them has the issue, instead of selecting “search current mailbox” click the dropdown and select the folder that incorrectly shows unread email. Then follow the rest of the instructions.

The solution is in the view settings. Make sure in the setting that hide files for deleting is not the selected. choose view all files. And all your files will start showing, before I got this I have done scanpst and a whole lot of other things. Andit is just a simple solution

I had 1 message in my inbox but could not find any emails I have not addressed.
My finding were; An end user created an calender event, she must have rescheduled a new event without deleting the original invite. That was all it was. I deleted that first event and all is good.

Additional note that might be helpful. I had a folder with symptoms that looked just like this. I had moved a folder from an IMAP account to a pst account in outlook 2016. Uh Oh, a lot of emails disappeared, but it showed a couple of thousand unread. I could convert to PDF and that at least retrieved the info. Tried all the fixes listed here as well as elsewhere. No Joy!.

Since I had a safety copy in the PDF, I said “caution to the wind” and just dragged it to another IMAP based account. Ta-Da, the “lost” emails showed right back up.I hate it when sync means “sunk” 🙂

I was having a headache with missing messages. My fix was actually right next to where he said. change view settings, It was set to hide marked for deletion and I changed that to imap and wham everything appeared. I changed for all folders
